Set of keys



The FIGURE is a front elevational view of a set of keys depicting our new design.

The design consists of the appearance, shape, arrangement, and relative placement of the individual buttons in a flat plane with no depth or contour.

The broken, dot-dash, lines immediately adjacent the shaded areas represent the bounds of the claimed design; the broken lines form no part of the claimed design. 

The ornamental design for a set of keys, as shown and described.
